1) We plan to travel swiss in June 2014 for 5 days, 2 adults and 20m baby. I guess 4 day swiss flexi pass would be better to order? As one day we plan to just cover Jungfrau mountain and I heard with flexi pass - between active days still we can get 50 % for Jungfrau mountain. As we would be staying near interlaken station so would be easy to make use of one day(between active day) to Jungfrau mountain with less other train/bus travel. And rest 4 day we plan to cover swiss cities from Interlaken. Please advise if this works? or we should go for any other pass?

2) Also I need help in planning rest 4 days. We are arriving at Geneva airport and departing from Basel airport. And we are staying all nights in Interlaken . We would like to cover glacier express in this trip. Please advise how to fit glacier express trip in one day from Interlaken?

1) A 4-day Swiss Saver Flexi Pass it a good choice. Indeed you can purchase discounted tickets to the Jungfraujoch on a non-free travel day. The trip to the Jungfrau is 50% discounted to Wengen or Grindelwald, and 25% off from there. Flexi Pass prices are listed on the Swiss Railways website. Further details are on our pass page. Whether another pass is cheaper can be checked as explained here.

2) You can't do the entire Glacier Express on one day from Interlaken. Do this in a relaxed way, one should spend the night in Zermatt and St. Moritz, or nearby. From Interlaken, you can only do part of it and it would still be a long day. I would not recommend that with a young child. Rather look into the Golden Pass line. You can easily cover that while traveling from Geneva to Interlaken (southern section) and from Interlaken to Basel (northern section).

You may be aware, but just in case: taking young children to high altitudes could be hazardous to their health, as explained on the Jungfraujoch page. Please check that before going.

Glad to help! Doing the Brig to Chur leg of the Glacier Express is possible, but you're still looking at a 10 hour day trip. That's really long with a baby I would say, but you can check the timetable and our Glacier Express page for travel and route details, and see if this is feasible for you.

The Bernina Express starts in Chur and goes to Tirano in Italy. This is also too far from Interlaken. See the timetable and Bernina Express page for details. The good news is that there's plenty to come back for after your trip ;-)

My comment about young children and the Jungfraujoch was not weather related. The trains are warm and you can stay indoors up there, so that's no problem. The issue is the lack of oxygen at that altitude, and the inability of children to express how they feel. Please see the page I referred to. Checking the weather forecast is good in any case, as clouds may block the views which are the main reason to go there.

That sounds great! Regarding the Schilthorn: that's only a little bit lower than the Jungfraujoch (see the Schilthorn page). You'd better ask your doctor what's save for your child. Without that information there are still plenty of lower viewing points to go to: Brienzer Rothorn, Niesen, Schynige Platte, for example.

I have another query for Mt. Titlis, we plan to visit either on 11th june or 12th june. But on their website they have mentioned about maintenance work in June- Chairlifts Trübsee - Jochpass -Engstlen -28 April - 13 June 2014 (http://www.titlis.ch/en/ski-resort/fahrplan-sommer). Does that means we can't take chairlift from mountain station to either the glacier park for snow rides or to suspension bridge for cliff walk?
